Abstract

The invention discloses a three-way vibration test sensor based on an additive manufacturing technology and a preparation method, and belongs to the technical field of detection. A center hole of a cylinder in a vibration test assembly of the three-way vibration test sensor based on the additive manufacturing technology is fixedly connected with a center rod of a base, and the lower end of a sensor shell is fixedly connected to a middle disc in the base. A data input end of a vibration signal acquisition card in the information management module is in communication connection with a data transmission interface of each induction assembly in the vibration test assembly, and a piezoelectric layer and a packaging body are manufactured by taking vibration guide liquid as a vibration conductionmedium and adopting an additive manufacturing technology. According to the invention, vibration wave conduction can be continuously carried out, the piezoelectric layer has high conductivity and sensitivity, the quality and quantity of collected vibration signals are optimized and improved, the manufacturing process is simple, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to a three-way vibration test sensor based on additive manufacturing technology and a preparation method. Background technique [0002] The vibration measurement sensor is an important branch of a wide variety of sensors. Its function is to quantitatively convert the vibration displacement, vibration velocity and vibration acceleration caused by vibration into electrical signals, record them and feed them back to the user. Due to the limitations of the development of material science and electronic measurement technology, the common vibration sensors today include fiber grating vibration sensors, piezoelectric vibration sensors and capacitive vibration sensors. Most of these types of sensors are based on traditional metal materials and semiconductor materials. There are some obvious deficiencies in manufacturing, such as: complex manufacturing process, not simple struc...
